Kubectl bash Autocomplete is broken with latest bash-completion version

[abhijit-dev82]

What happened: kubectl autocomplete is broken with the below error "bash: _get_comp_words_by_ref: command not found" with 2.14 Bash-completion version. From the bash-completion docs "_get_comp_words_by_ref" seems to be a deprecated API.

What you expected to happen: Bash Autocomplete to work as for older versions.

How to reproduce it (as minimally and precisely as possible): Install latest "bash-completion" package and try out "kubectl" autocomplete.
